HEATING SYSTEM.

Application mea August 2 9, 1923. serial No. 659,968.

To all whom it may. concern: l

Be it known that I, ADoLrH F. ROTH, a

I citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in a Heating Systcm, of which the followingis a full, clear, and exact speciication.

lThis invention relates more particularly to a class of heating apparatus.

My invention has for its object primarily to provide a simple and efficient system or apparatus designed to be employed for heating the rooms' or chambers of buildings, cars, boats and elsewhere in a manner whereby the -volumeof heat units will be circulated in the lower part of the chamber by preventing tendency of the heat units to rise to thew upper part of the chamber, in order to avoid waste of heal units as well as accomplishing an effectual heating of the habitable portion of the chamber prior to the heating of its upper part. The invention also contemplates exhausting in part the heated atmosphere in the chamber at inten vals for enabling the temperature to be maintained ata desired degree of heat and which provides a proper circulation of atmosphere in the chamber. These advantages are accomplished by means providing a flue or duct adapted to be arranged inthe upper part of the chamber, and the duct has an inlet for intake of air as well as having an outlet'for delivery of air intothe upper part of the chamber. A normally open elec.- tric circuit leads to part of the duct, and in terposed in the circuit are resistance coils serving a means for heating when the circuit is closed, the air flowing through the duct from its inlet to its outlet. In the duct between its inlet and outlet is a fan adapted to be disposed in the upper part of the chamber, and this fan is operable with the clos-l ing of the circuit for eausin the heated air in the chamber to circulate ownwardly toward the lower part thereof so that the volume of heat units will first collect in this portion of the chamber instead of collecting 1n its upper part.-

Other objects of the invention are to provide means for regulating the current delivered to the resistance coils whereby the heat units from -the coils may be controlled; to provide a flue or duct ada ted to be arranged in the lower part of t e chamber for serving as an air outlet; and to provide a .second fan which is operative with the c1osing of the circuit to exhaust the heated air in the lower part of the chamber at desired intervals.

With these and other objects in view, the invention will be hereinafter more fully explained with reference to the accomnanving drawing forming a part of this specification in which similar characters of reference indlcate corresponding parts 1n all the views,

and will then be pointed out in the claims at vthe end ofthe description.

In the drawing, Figure 1 is a fragmentary i view' showing a detail section, partly broken away, taken through the room or chamber of a building or elsewhere with an illustrative form of my heating system applied thereto, an

Fig. 2 is a diagrammatic view of the electric circuit which maybe used in the system. l The heating svstem has a mixing chamber or casing 10 which may be o fany desired shape and size to permit of bein mounted above the central part of the ceiling, as 11, of a room or compartment or chamber, as 12, of a building, car or boatand elsewhere, the room having a 'loor, as 13, and walls, as 14, l5. In the lower part of the mixing chamber 10 is an opening 16 which servesl as an loutlet leading into the room 12, and suspended from and spaced below the ceiling 11 may be a dome, as 17 of an ornamental design for screening the outlet 16 of the mixing chamber 10. Above the ceiling 1l of the room or chamber 12 and leading into the mixing chamber 10 from and through the side wall 15 of the room is an air feed flue or duct 18. preferably in the form of a pipe having its end at. .the exterior of the side wall serving as an inlet 19 for intake of air for passage into the mixing chamber 10 through the flue or' duct or pipe. From an opening in part of the mixing chamber l0 opposite tothe duct or pipe 18,'and above the ceilingof the room'12, leads an air delivery or circulating flue or duct 20 in the form of a right angled pipe having its elbow part extending through an opening inthe* be another air delivery or circulatin flue or duct 22in the form of a right-angle pipe r, having one of its arms extending to the side the flue 18 into the mixing chamber v10 asv well as permitting air to be delivered from the central parts of the interior of the room through the iiues 2 0 and 22 into the mixing chamber. y

The air is delivered to the mixing chamber 1C through the ducts through the medium of a suctional fan, as 24, which may be of any suitable type, though'the form of the fan I prefer to employ is dis closed in my pending application for a patent, serially numbered 642,522, filed May 31, 1923, and this fan is bracketed, as at 25, to the ceiling of the room so that its blades.,

`as 26, are dis osed at or within the outlet 16 of the mixing chamber between the ceilin and the dome 17. rllhe fan 24 is referaby driven by a suitable motor, as 2 having the fan keyed on its shaft, and the motor is of a form adapted to be driven by the current of an electric circuit, as 29. The

' circuit 29 may derive its current from any suitable source of electrical energy, as 30, and in the feed duct 18 is a resistance coil 31 of an appropriate type which' is interosed in the circuit for heating the air ed into the mixing chamber from the ex-Y y 'motors Switches, not shown, may be proterior of the room through the duct 18. The heated air delivered into the 'chamber from the duct 18 will also be mixed with the air delivered through the ducts'20 and 21 by the operation of the fan 24 when the fan is driven, as will be hereinafteri more fully explained. interposed in the circuit 29 and arranged on a suitable part of one of the walls interiorly of the room 12\may be a thermostat, as 32, of any well known or preferred make for operating to regulate the electric current for controlling the heat units of the resistance coils 3l, in order to regulate the heating of the air in the mixing chamber so that the air when delivered into the room will be at a proper temperature.

" In the lower part of the room 12 may be provided a flue or duct, as 33, so that part of the air in the room may be exhausted at desired intervals. The duct 33 is preferably in the form of a pipe having its inlet end 34 leading from the room through an openingin the central part of the floor 13. The duct or pipe 33 may be disposed under the `loor so that it extends through an opeliingv tiona in the side wall of the room, and the second end of this duct provides an outlet 35 exteriorly of the room. On the outlet end 35- may be a box or casing, as 36, having openings, as 37, 38, in spaced parts of its wall, andv in the casing 36 is mounted a fan 39 which is preferably of a' form similar to the fan 24, above referred to, for being adapted when operated to suctionally exhaust air fromA the lower part of the room. The fan 39 is mounted on the shaft of a motor 40 arranged within the casing so that the fan is disposed for causing discharge of the air through the openings 37, 38 of the casing 36.

The motor 40 is interposed in the electric circuit 29 which may consist of a Wire 41 leading from the source of electrical energy 30 to the resistance coils 31, and also Afrom the resistance coils is a wire 42 leading to one pole of the thermostat 32. From the second pole of the thermostat. is a wire 43 leading to one pole, vas 44, pf, a suitable switch, as 45, and from the second pole of the switch is a wire 46 leading to the source of electrical ener y 30. Connected to the wire 42 is one en of a wire 47 leading to one of the terminals of both of the motors 27 and 40, and connected to the wire 41 is a wire 48 leading to the second terminals of the motors. When the switch 45 is closed on the pole 44 the ircuit will be closed from the source of lectrical energy over the wires 41, 48 to the motors 27, 40, and

to the resistance coils 31. The circuit will also be closed from the source of electricah energy over the wire 46, through the switch 45, over wire 43, through the thermostat 32, over wire 42 to the resistance coils and over wire 47 to thesecond terminals of the vided on the motors for cutting-in and cutting-out either of the motors from the cir cuit at desired intervals, and with the driving of the' motors the fans 24 and'29 will be operated whereby the fan 24 will sucly force fresh air through the duct 18 into the mixing chamber, and this air will be heated byv the resistance coils 3l. Air from the interior of the room 12 will also be suctionally forced through the ducts 20 and 22 intothe mixing chamber so that all the heated air will pass through the outlet 16 of the mixing chamber into the upper .part of the room. With the operation of the fan 39 air from the lower part of the room will be suctionally vforced through the duct 33 for exhausting the air fan 26 inl or er that the power of the fan 39 will not alone exhaust the cold air 4:from

the lower part of the chamber, but will also upper Dart to the lower part of the chamber. Meanwhile the suctional action of the fan 26 will through the medium of the flu'es 2l and 23 further cause the air to circulate, and with a constant replenishin of fresh air through the inlet pipe 18 toget er witha determined exhaustion in the process `by proper regulation of the fans a thorough4 circulation and uniform temperature will be maintained in all parts of the chamber without waste of heat units.

In thev foregoing description, I have embodied the preferred form of my invention, but- I -do not Wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages lof' this invention, therefore, I reserve to myself the right to make vsuch changes as fairly fall within thev scope thereof.
